Cannot get rid of small offset between sketch origin and housing origin

[hoosac19]

Hello,

I finished my housing component and moved its origin to coincide with the assembly origin as accurately as I could, and then grounded this component (see the "housing origin shown" screenshot).  However, the sketches that I used to construct the housing features somehow got offset from the housing origin by about 0.02mm (see the "sketch origin shown - housing view" screenshot).  Note that all the features in my sketches themselves were purposely set to whole mm (occasionally to 0.1mm) - see the "sketch origin shown - edit sketch view" screenshot for one of these sketches.

I don't know how this happened and have been unable to make the sketch origin and housing origin coincide, could you please advise me on what I should do?

Thank you very much!

Simple fix, 

Delete all Capture Positions to the left of this mark, (done) Delete all the stuff to the right of this mark. (up to you)

Your assembly will bounce back to the document origin, the ground and Joints will work as expected.

After making the joint, delete the Capture position as you go.

Might help....
